COOKING-STOVE.

' SPECIFICATION formingpart of Letters Patent No. 431,158, dated July 1,1890.

Application filed June 5, 1889. Serial No. 813,135. (No model.)

To all whom it may concern:

Be it known that I, WVILLIAM H. OOL- DRIDGE, a citizen of the UnitedStates, residing at Birmingham, in the county of J efferson and State ofAlabama, have invented a new and useful Cooking-Stove, of which thefollowing is a specification.

This invention has relation to cookingstoves; and among the objects inview are to provide for a circulation of cold air around the fire-box,through the top and cross-pieces of the stove, whereby the life of thestove is extended, and the parts usually subjected to intense heat aremaintained at a reasonable degree of temperature.

The invention consists in certain features of construction hereinafterspecified, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a plan of a stove constructed inaccordance with my invention. Fig. 2 is a side elevation. Fig. 3 is acentral vertical longitudinal section on line 50 cc of Fig. 1. Fig. 4 isa perspective of the two top sections of the stove. Fig. 5 is a similarview in detail of the stove plate or lid. Fig. 6 is a similar view ofthe fire-back.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 represents the side walls of the stove, 2 the oven-door, 3 thefirebox, and 4 the ash pit, all of the usual construction.

6 represents the front top section of the stove, and 7 the rear topsection, each of which is provided with its respective removablecross-pieces 8 and 9 and pot-holes 10 at each side thereof. The rearedge of the section 6 is provided with a transverse downwardly dependingoffsetted portion 11, extending from side to side thereof, which portionis perforated or not, as desired, as at 11*, and at its center andopposite sides provided with laterally-disposed similar offsettedportions or branches 12. Upon the under side of the cross-pieces 8 and 9there are provided longitudinally-disposed closed passages 13, whichregister and communicate with the adjacent branches 12, said passages 13being open at both ends.

The section 7 is provided with, at its inner edge, an overlappingportion or plate 14, designed to take'into a recess 15, formed at theinner edge of the offsetted portion 11, which latter portion, inconjunction with the plate 14, forms a lateral passage open at both endsand communicating with the outer atmosphere by perforations 16, formedin the plate 14. The branches 12, extending from the passage 11, arecovered by a projecting plate 17, extending from the edge of the plate14.

Each of the stove-holes 10 at its outer sides or edges is provided withrecesses 18, having a central perforation 19.

20 represents the stove-plate, which at one side is provided withalaterally-proj ectin g arm 21, upon the under edge of which depends anL-shaped lug 22, designed to be received by the perforation or opening19, formed in the recess 18, said recess being of a size and shape toreceive the arm 21. By this it will be seen that when the plates 20 arenot in use or serving their well-known function they may be partiallyrevolved or rotated upon the lug 22, so as to project laterally from theside of the stove-top and serve as convenient shelves for the support ofpets, pans, and other articles which it is desired to set aside, and inthis manner I increase the area of my stove-top.

22 represents the fire-back, and the same is arranged in rear of thefire-box 3, and consists of two sections 23, each of which is acounterpart of the other, said sections being bolted together by bolts24 and consisting of opposite registering offsets or corrugations 25,extending from each edge or side of the plates and slightly curvedupwardly and to the center and terminating in the vertical fine 26,which is slightly curved or offsetted, as at 27, to communicate with anopening 28, formed in the center of the offsetted passage 11 andintermediate the two branches 12 thereof. Perforations 29 are formed oneach side of the stove and permit cold air to pass through. the passages25 up into the flue 27, through the passage 11, and out through thebranches 12 into the passages 13 of the crosspieces 9, and thussufficiently cool the stove.

The hot air that passes into the fire-back is discharged through theopenings 16, formed in the rear top section 7, or, if desired, back intofire-box.

The oven-door 2 is provided at its upper rear corner with a pintlerod30, which takes the place of the usual pintle or bolt. Said rod isextended through an opening or slot 3l,forrned in the stove-top, andterminates in a handle 32, projecting above the top, whereby said doormay be operated from above the stove and without the necessity ofstooping, as is usual. A boss 33 is formed upon the operating-rod '32above the opening 31 and serves to cover that portion thereof unoccupiedby the pintle-rod 30. The rod 30 is also provided with a recess or slot34 for the reception of a poker or lifter adapted to operate the door inlieu of the handle 32.

Openings, as 34, may be formed in the rear section of the fire-back forthe purpose of ventilating the oven, said openings preferably beingcovered with a suit-able screen of wire-gauze.

Having described my invention, what claim is 1. The combination, withastove, of a stovetop formed in sections, one of which overlaps theother, the opposite section being provided with a transversely-arrangedpassage having opposite branches covered by the opposite section, and ofcross-pieces mounted in the stove openings and provided with openendedair-passages communicating with the branches, substantially asspecified.

2. In a stove, a fire-back provided with a series of lateralair-passages communicating with the exterior and terminating in avertical flue, substantially as specified.

3. In a stove, a fire-back formed of opposite sections havingair-passages communicating with the atmosphere and terminating in acentral passage, in combination with a stove-top having a transverseair-passage communicating with the vertical flue of the fire-back andhaving opposite branches, substantially as specified.

4. In a stove, a fire-back provided atopposite sides of its center witha vertical series of laterally-disposed air-passages and at its centerwith a vertical passage, the inner ends of the lateral passagescommunicating therewith, substantially as specified.

5. The combination, in a stove, of the fireback 22, having theinwardly-disposed series of oppositely-located air-passages 25,terminating in the central flue 27, with the top of the stove formed insections 6 and 7, the section 6 being provided with the offset 11, thecentral opening 28, receiving the flue 27, and the opposite branches 12,and the section 7 having the covering-plates 14 and 17, perforations 16,and the cross-pieces 8 and 9, having air-passages l3 communicating withthe branches 12, substantially as specified.

6. The stove-top 6, having the opening 10, depression or recess 18,formed at one side and extending therefrom, said recess 4 having theperforation 19 formed in its bottom, in combination with the plate 20,having the arm 21 fitting the recess, and the L-shaped lug 22, insertedin the perforation, the shank of the lug acting as a pivot for theswinging of the plate, substantially as specified.

7. The fire-back consisting of two similar sections 23, bolted togetherand formed with opposite registering offsets or corrugations 25,

- forming air-passages terminating at the center in the vertical flue27, as set forth.

8. The sections 6 and 7, the first mentioned provided with the offset 11,havingthebran ches 12, and the latter with the plate 1& and projectingportion 17, covering the offset and branches and forming air-passages,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto atfixedmy signature in presence of two witnesses.
